Oops, beat me to it. I was just waiting to add the medium rez results. :)

Anyway, a little bit of information about my setup. This is a Pak 68/3 board,
installed (it would be more accurate to say "stuffed"!) into my STacy.

I bought this board off Ebay cheap (less than $100). Of course, there's a
catch. When I got the board, several of the pins on the underside were
missing or sheared off. It looked to me like someone had removed it
from a previous installation with *prejudice*. So I initially had Alex at
ATY Computers do some repairs but eventually had to do some of my
own. It worked, but I've never been able to get it to run reliably above
40mhz. When I switch the oscillator to 50mhz it will boot up and run
but it's unstable. Random software crashes (none fatal but still rather
annoying) and glitches. It is rock-solid at 40mhz though so I settled for
that.

I do not have a Frak2 or PuPla2 board installed so it's just ST-RAM.

Maybe someday. :)

Here's a couple of pics showing the damaged state the board was in when
I received it. I did give the seller a bad rating. He cried and whined about
it no end, complaining that since I did get it working and it was sold to me
cheap, I had no right to complain.

Whatever. :)

Still curious as to why the "Floating Math" stays at zero?

The board does have a working 40mhz 68882 FPU.

Thanks.

The only benchmark file with FPU is the Falcon one.. You're using a STE file which doesn't have a FPU normally, so no data exists to compare it to, thus zero.

Hmm, so could I run it against the Falcon as a benchmark instead of the STe and see the results?

Thanks.

Okay, same setup, hi-res, stacked up against a Falcon.

Older message thread but running Gembench on my Pak 68/3 equipped
Atari STacy always makes me smile... :)
